Andy Ramey, Ph.D.
Through my service at the USGS Alaska Science Center, I support the development and application of genetic and genomic tools to advance molecular ecology research pertaining to wildlife health and disease, population genetics, and environmental DNA. Research in the Molecular Ecology Lab promotes informed decisions regarding the conservation of fish and wildlife resources.
I currently serve as the Director of the Molecular Ecology Lab at the USGS Alaska Science Center. The team of scientists working in the Molecular Ecology Lab develops and applies tools to obtain information on the health, distribution, and genomic characteristics of biological natural resources. This includes collecting and interpreting data on the health and disease status of fish and wildlife, the genetics of animal and plant populations, and the distribution of animals and pathogens using environmental DNA. We use this information to help partners and the public to make informed decisions regarding the conservation of fish and wildlife resources.

Maintenance and dissemination of avian-origin influenza A virus within the northern Atlantic Flyway of North America
Wild waterbirds, the natural reservoirs for avian influenza viruses, undergo migratory movements each year, connecting breeding and wintering grounds within broad corridors known as flyways. In a continental or global view, the study of virus movements within and across flyways is important to understanding virus diversity, evolution, and movement. From 2015 to 2017, we sampled waterfowl...
